You’re developing an application that will need to do the following.
· Upload images via a front end from users.
· Store the images in S3.
· Add the location of the images to a DynamoDB table.
Which of the following two options would be part of the implementation process? Please choose two correct answers.

Answer options:

A.Add a Lambda function that would respond to events in S3.
B.Add a message to an SQS queue after the object is inserted into the bucket.
C.Ensure that the Lambda function has access to the DynamoDB table.
D.Ensure that the SQS service has access to the DynamoDB table.

Answer – A and C
The ideal approach would be to automate the entire flow using AWS Lambda. Ensure that the Lambda function has a role to access data in the DynamoDB table.
The AWS Documentation also mentions the following.
You can write Lambda functions to process S3 bucket events, such as the object-created or object-deleted events. For example, when a user uploads a photo to a bucket, you might want Amazon S3 to invoke your Lambda function so that it reads the image and creates a thumbnail for the photo.
You can use the bucket notification configuration feature in Amazon S3 to configure the event source mapping, identifying the bucket events that you want Amazon S3 to publish and which Lambda function to invoke.
Options B and D would not be the ideal combination for this sort of requirement.
